Luxair Automatic Airtight Wall Vent — 125mm (5") and 150mm (6")

The Luxair Automatic Airtight Wall Vent seals shut automatically when your extractor fan is switched off, preventing warm air from escaping through the wall duct and cold air from entering. It operates entirely by air pressure — when the extractor runs, the pressure opens the vent; when the extractor stops, low-maintenance springs return the vent to the sealed position. No electricity, no sensors, no maintenance beyond occasional cleaning.

How It Differs From a Standard Wall Vent

A standard wall vent uses a simple gravity or spring flap that provides minimal sealing — warm air escapes around the flap and wind pressure can force cold air back through the duct into the kitchen. The Luxair automatic airtight vent uses a full perimeter seal on the exterior cover, closing flush against the wall surface for maximum heat retention. Internal guide vanes reduce back-pressure within the duct run, improving extraction efficiency and reducing operating noise compared to a standard vent outlet.

Installation Guidance

For optimum performance this vent is recommended for use with cooker hoods rated above 650m³/hr — the motor needs sufficient airflow pressure to open the vent fully. Use with 125mm (5") or 150mm (6") ducting and keep the total duct run under 4 metres for optimal airflow and heat retention performance. Suitable for airtight and energy-efficient homes where standard wall vents create unacceptable heat loss.

Ducting Size Guide

Selecting the correct ducting diameter for your motor output ensures maximum extraction performance:

  • Below 450m³/hr → 100mm (4") ducting
  • 450–750m³/hr → 125mm (5") or 150mm (6") ducting
  • 750–2,000m³/hr → 150mm (6") or 200mm (8") ducting

✓ Automatic airtight seal — vent closes flush against external wall when extractor is off; prevents heat loss and cold air entry

✓ Fits 125mm (5") and 150mm (6") round ducting — check product title for exact size before ordering

✓ No power required — fully mechanical operation using extractor airflow pressure to open; springs return vent to sealed position

✓ Stainless steel exterior cover — sleek round finish, flush-mounted against external wall with full perimeter seal

✓ Guide vanes reduce back-pressure — improves extraction efficiency and reduces operating noise versus standard wall vents

✓ Quiet and reliable — durable low-maintenance springs and joints; smooth silent operation in windy conditions

✓ Recommended for hoods above 650m³/hr — requires sufficient airflow pressure to open vent fully

✓ Recommended duct run under 4 metres — keeps airflow resistance low for optimal heat retention and extraction performance
